Miele Dishwasher Error Code F78

How to fix Miele dishwasher error code F78

If you see the error code F78 on your Miele dishwasher, it means there is a problem with the circulation pump. This will cause the dishwasher to stop working properly and activate the drain pump as a safety measure.

How to resolve the error code F78

1. Heat 2 cups of warm tap water in the microwave for 3 minutes (approximately 150-160°F).
2. Remove the filter assembly from the bottom of the dishwasher.
3. Pour the hot water into the dishwasher sump and add 2-4 drops of rinse aid.
4. Let it sit for 5-7 minutes.
5. Access service mode and clear all fault codes.
6. Start a new cycle after the time has elapsed. The hot water/rinse aid will drain out.
7. The circulation pump should start after the dishwasher fills with water (approximately 2 minutes).
8. If the pump hasn’t started after 2 minutes, repeat the hot water/rinse aid mixture.
9. If the pump still doesn’t start, arrange for a service to replace the pump.
